Flash and Excel?

Is there a way to use Flash/AS to take the math logic built into an exel document and import that functionality into Flash to make a very simple flash tool.

Basically, the excel sheet is simply a forecasting tool, used to estimate financial impacts on subtle adjustments in a handful of components in a marketing strategy. If I could lift the functionality and algorithms from the Excel sheet (or maybe export as XML?) and pull that into Flash.

Has anyone encountered/used a tool or method to do this?

Thanks for your time!
